尽管近年来GLP-1减肥药赛道拥挤不断，但是仍然有企业能够脱颖而出，融到资金。 近日，新晋减肥药公司Metsera宣布了2.15亿的B轮融资，这距离该公司今年4月份2.9亿美元的A轮融资仅仅过去7个月，Metsera显然有从竞争环境中脱颖而出的潜力。 卖点：轻微副作用，不涉及剂量渐增，每月一次 从该公司9月发布的I期临床信息来看，Metsera目前进度最快的管线是长效可注射GLP-1受体激动剂MET-097，该管线采用Metsera的HALO脂质平台设计。注射间隔为每个月一次，接受MET-097i治疗的参与者在第36天的体重比基线下降了7.5%。 比较值得称道的是该药物的安全性效果。一般而言，已批准的减肥药需要通过滴定的缓慢增加剂量来适应剂量的时期，不然就可能出现胃肠道相关副作用。比如说，例如，司美格鲁肽一般被建议从0.25mg小剂量起始，单次注射逐步增加到1mg。 而相比于目前市面上的司美格鲁肽和替尔泊肽，MET-097的临床不需要涉及剂量渐增，而且副作用看上去非常轻微。 这一方面简化了患者的给药模式，另外一方面还优化了安全性问题。 另外，该公司还有该公司有一个完整的营养刺激激素(NuSH)模拟肽库，该肽库建立在大约2万种NuSH模拟肽的基础上，并通过二十年的经验生物学研究和先进的肽工程开发而成，可从中推出多种药物候选物，目前该公司还有MET-034i，MET-233i等管线。 目前推测，技术来源于收购GLP-1研究的领军人物Stephen Bloom的小微公司Zihipp和韩国公司D&D Pharmatech。 在这种情况下，吸引多位高端投资者的两轮次融资似乎再正常不过，值得一提的是，如果查看Metsera的技术团队，会惊讶地发现CSO是以前一家中国药企的联合创始人之一。 CSO此前是国内企业创始人 如果仔细看Metsera的技术掌舵团队，会发现此前与中国Biotech安济药业（Anji Pharma）的一致之处都是CSO Brian Hubbard，研发负责人（转化医学）的Mike Serrano-Wu。这两位显然都是新药猎人“老兵”。 安济药业此前是由CRO公司维亚生物所孵化的，董事长也是维亚生物的创始人毛晨博士。CEO是现在博致生物首席运营官宗宜伟博士。 当时具有的管线是收购自Elcelyx Therapeutics的ANJ900（二甲双胍延迟释放新剂型）和授权自诺华的DGAT1抑制剂ANJ908（pradigastat），授权自LipimetiX Development（Capstone Therapeutics子公司）的多肽创新药AEM-28。适应症方面，ANJ900旨在针对那些有着慢性肾病的二型糖尿病患者，ANJ908主要用于便秘，AEM-28用于严重的孤儿高胆固醇血症。 值得一提的是，维亚生物孵化的另外一家企业 Dogma Therapeutics的技术骨干也是Brian Hubbard和Mike Serrano-Wu，Dogma开发的主要是PCSK9小分子药物，目前已经授权给了阿斯利康，研发代码为AZD0780。 总结 总的来说，Metsera的崛起速度非常之快，收购管线抓住了现有药物的弊端，做出了差异化，技术团队选取了新药猎人“老兵”掌舵，可以期待未来该公司的更多信息。 参考来源： https://metsera.com/news https://www.sohu.com/a/594125812_120455786 https://www.dogmatherapeutics.com/

- TTX-810 is designed for rapid clearance to circumvent mechanism-based risks of MCL1 inhibition - High potency affords robust anti-tumor effects whilst preserving cardiomyocyte viability - Trueline Therapeutics on track to initiate clinical development of TTX-810 CAMBRIDGE, Mass., & BERLIN--(BUSINESS WIRE)-- Trueline Therapeutics Inc., an oncology-focused subsidiary of Anji Pharmaceuticals, today announced the successful completion of IND-enabling studies with MCL1 inhibitor TTX-810, a highly potent and selective macrocyclic compound to treat patients with solid tumor or hematological cancers. A distinguishing feature of TTX-810 is a rapid clearance pro minimize the potential risks of sustained MCL1 inhibition in non-cancerous tissues. “The completion of IND-enabling studies marks the culmination of over a decade’s work to truly understand the safest and most effective way to approach MCL1 inhibition,” said Ulla Rauh, Ph.D., CEO/CSO of Trueline Therapeutics. “With our rapid-clearance strategy further de-risked, we are excited to progress TTX-810 into cancer patients and finally unlock the therapeutic potential of MCL1 inhibition.” TTX-810 was discovered by a partnership between the Broad Institute of Harvard and MIT and Bayer Pharmaceuticals. The exquisite potency of TTX-810 was achieved by structure-guided design and comprehensive profiling versus over 500 cancer cell lines to define the optimal cellular context for rapid and selective induction of cell death. Following candidate selection, Trueline Therapeutics scientists designed and executed the IND-enabling program in preparation for first-in-human testing. “When we first saw the TTX-810 data package, our key questions were ‘Will it work?’ and ‘Will it be safe?’ given the challenges other therapeutic candidates with more traditional clearance profiles are encountering,” said Michael Serrano-Wu, Ph.D., Chief Scientific Officer of Anji Pharmaceuticals. “This approach benefits from the rapid and irreversible effects of MCL1 inhibition, which we believe offers a therapeutic window not attainable with longer-acting compounds. We customized our IND-enabling program to address these questions, and now it is full steam ahead to demonstrate the clinical advantages of this unique profile.” About Trueline Therapeutics Inc. Trueline Therapeutics is an oncology-focused subsidiary of Anji Pharmaceuticals. In addition to the MCL1 inhibitor TTX-810, TruelineTx is developing a CD3/CD33 bi-specific called TTX-564 which has been shown to be safe in cancer patients and induce strong depletion of immunosuppressive cells called myeloid-derived suppressor cells (MDSCs). A dual HCK/BTK inhibitor, TTX-114 is in preclinical development. For more information visit . About Anji Pharmaceuticals Inc.
